Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, based on the examples herein, which are within the scope of the invention as defined by the claims, will be within the scope of the invention as defined by the claims.
In the description of the present invention, it should be understood that the terms "center", "length", "width", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "side", etc. indicate orientations or positional relationships based on the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention. In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.
The embodiment of the invention provides a movable operation cabin structure, which can prevent an operation cabin from shielding the sight of a driver in a cab on an operation vehicle body.
The technical solution provided by the present invention is described in more detail below with reference to fig. 1 to 9.
Referring to fig. 1, fig. 1 is a schematic view of a robot arm on a conventional track working vehicle working on the right side of a track in the prior art. In the conventional rail vehicle, when traveling, a driver is required to drive the vehicle body 100 on the rail 400 at a high speed in the cab 101 until the vehicle is stopped at a designated working place. In road operation, the base on the work vehicle body 100 can rotate and slowly move on the vehicle body, and in the state shown in fig. 1, the base rotates on the work vehicle body to enable the mechanical arm 300 to work on the road surface on the right side of the track 400. The base moves on the work vehicle body 100, and can work on a road surface in a certain area. The connection structure between the base and the working vehicle body is not described here in detail.
Because the track operation vehicle needs to operate the road surface on two sides of the track, the common operation vehicle in the prior art, the equipment operation cabin 200 is fixed on one side of the mechanical arm, referring to fig. 1, when the vehicle operates on the right side of the track 400, the equipment operation cabin 200 is located on the right side of the mechanical arm 300, so that a better view is provided for the right side area of the mechanical arm 300, and an operator can clearly observe the condition on the side of the track, so that the mechanical arm 300 can be conveniently and safely operated. However, when the left side of the track is required to be worked, the operator in the equipment operation room 200 is blocked from view by the robot arm, and at this time, the operator cannot observe the left side of the robot arm 300 well. Usually, the camera is used for monitoring or manual command to assist, so that a driver is helped to observe the situation of the position shielded by the equipment operation cabin 200, but the camera cannot completely replace the real restoration construction environment of human eyes, only has limited auxiliary effect, and still has great potential safety hazard.
Aiming at the problem that the arrangement of an equipment operation cabin in the prior art can influence the operation vision of an operator, in order to ensure that the operator has a better operation vision of the mechanical arm, the arrangement of the equipment operation cabins on the left side and the right side of the mechanical arm is considered.
However, if one equipment operation cabin is provided on both the left and right sides of the robot arm, new problems are brought about. Referring to fig. 2, fig. 2 is a schematic view showing a state in which a rail working vehicle having two equipment operation cabins is traveling on a rail. Because the two operation cabins are fixedly arranged on the left side and the right side of the mechanical arm 300, operators in the operation cabins of the equipment are convenient to have better operation vision of the mechanical arm 300, but the following problems are brought: referring to fig. 2, the direction of the dashed arrow in fig. 2 indicates the direction of the line of sight of the driver located in the cab 101 of the vehicle body, since the driver needs to drive the vehicle body along the track 400 at a high speed in order to reach the designated work site, the robot 300 is in a collapsed state during the high-speed running of the vehicle, and no matter what angle the equipment operation cabin 200 is located, there is always one equipment operation cabin 200 that obstructs the line of sight of the driver in the cab 101. Referring to fig. 2, at this time, the sight line of the driver in the cab 101 is partially blocked by one of the equipment operation cabins, so that the driver cannot effectively predict the road condition ahead and cannot safely drive, which causes a potential safety hazard.
Therefore, if one equipment operation cabin 200 is directly fixed to each of the two sides of the mechanical arm 300, the operator in the operation cabin can have a good view, but the view of the driver in the cab 101 on the work vehicle body 100 is affected, and the safety hazard still exists in the rail work vehicle all the time.

Example two
In the first embodiment described above, a specific implementation of the movement of the cabin 10 along the guide rail 2 is provided, so that the cabin 10 can be moved from one side of the robot arm 300 to the other side on the base 1. However, in order to facilitate handling of the robot arm 300, the front side of the cabin 10 should be directed in the direction of the robot arm 300. If the cabin 10 is moved only from one side of the robot arm 300 to the other side along the guide rail 2, there may be a problem in that the front side of the cabin 10 cannot be directed toward the robot arm.
In view of the above, the present embodiment is improved on the basis of the first embodiment, and the supporting and rotating mechanism of the present embodiment further includes a self-rotating assembly rotatably connected to the support frame 3 and connected to the operation cabin 10, so that the operation cabin 10 can rotate on the support frame 3.

The operation cabin 10 is supported by the support frame 3 to move between the two fixing frames 11, and when the support frame 3 is close to one of the fixing frames 11, the operation cabin 10 can have a better mechanical arm operation visual field on one side of the mechanical arm when being locked at the position; when the support frame 3 is close to the other fixing frame 11, the operation cabin 10 can have a better operation view of the mechanical arm on the other side of the mechanical arm when locked at the position.
In the movable cabin structure in the embodiment, only one cabin 10 is arranged on the base 1, and the cabin 10 is movably arranged on the guide rail 2 of the base 1 under the drive of the supporting rotation mechanism. When the working vehicle body runs on the track at a high speed, the operation cabin 10 can be rotated to a position where the sight of a driver in the cab of the working vehicle body is not blocked, so that the working vehicle body can be ensured to safely run to a specified place on the track.
When the operation vehicle body runs to a designated place and the right side road surface of the track is required to be operated, at the moment, the operation cabin 10 is borne by the supporting and rotating mechanism to rotate to the right side of the mechanical arm on the base 1, the operation cabin 10 is pushed when the support frame 3 moves to be close to the fixed frame 11 on the right side of the mechanical arm, the front side of the operation cabin 10 faces the mechanical arm, and the operation cabin 10 is locked with the fixed frame 11 by inserting locking pins into the bottom of the operation cabin 10 and the locking holes 7; in this position, an operator in the operation cabin 10 can completely and clearly see the overall working condition of the mechanical arm on the right side of the track, so that the mechanical arm can be safely operated. If the left road surface of the track needs to be operated, at this time, the supporting and rotating mechanism is used for bearing the operation cabin 10 to rotate to the left side of the mechanical arm 300 on the base 1 (the motor rotates, the gear part 4 is meshed with the rack part on the guide rail 2 to drive the support frame 3 to move along the guide rail 2) until the support frame 3 is close to the other fixing frame 11 on the left side of the mechanical arm 300, the operation cabin 10 is pushed, the front side of the operation cabin 10 faces the mechanical arm, and locking pins are used for being inserted into the bottom of the operation cabin 10 and the locking holes 7, so that the operation cabin 10 is locked with the other fixing frame 11 on the base 1; in this position, an operator in the cabin 10 can completely and clearly see the overall working condition of the mechanical arm 300 on the left side of the track, so as to facilitate the safe operation of the mechanical arm.
Thus, when the manipulator 300 works, the manipulator 10 can obtain a better construction field of view by rotating the manipulator 10 on the base 1 and rotating the manipulator on the support frame 3, regardless of whether the manipulator works on the right road surface of the rail or the left road surface of the rail. When the construction is completed, the operation cabin 10 is moved to a position where the sight of a driver in the cab of the operation vehicle body is not blocked, so that the operation vehicle body can safely run on the track.
The embodiment provides a track operation vehicle, which comprises a operation vehicle body and the movable operation cabin structure, wherein a cab is arranged on the operation vehicle body.
According to the track operation vehicle, the position of the operation cabin can be quickly moved at any time according to the requirements of a construction site, so that the optimal working view during operation of the mechanical arm and the optimal running view during running of the operation vehicle body are achieved, the working efficiency is improved, and the working danger is reduced.
